One of the 219 schoolgirls seized more than two years ago found in Sambisa Forest area of Borno state, reports say.

One of the 219 schoolgirls abducted in Chibok in northeast Nigeria has been found, the first such development since their seizure by Boko Haram more than two years ago, according to activists, the head of a support group and a community leader.

Boko Haram, an armed group fighting against Western influence, has been waging a campaign against the Nigerian government for the last several years, attacking both Christian and Muslim targets.

Tsambido Hosea Abana, a Chibok community leader in Abuja from the #BringBackOurGirls pressure group, said on Twitter on Wednesday that the girl was found by civilian vigilantes in the Sambisa Forest area of Borno state on Tuesday.

Yakubu Nkeki, head of the Abducted Chibok Girls Parents' group, and Ayuba Alamson Chibok, a community leader in the town, also gave the same account to AFP news agency.

The girl was apparently found wandering in the forest. She is reportedly 19 years old.

The young woman was apparently brought to Chibok on Tuesday night and reunited with her mother. Her father was said to have died while she was held captive.

"She was carrying a baby but I do not know whether it is a boy or girl," Zannah said by phone from Chibok," Lawan Zannah, secretary of the association of parents of missing Chibok girls, said.
